Abstract
Method and apparatus are described for conducting a secondary game at a gaming device. In various embodiments, a player may acquire equity in the secondary game in such forms as a location of a game character, a number of symbols aggregated, a degree of completion of a puzzle, or a defensive provision. Certain symbols or outcomes in a primary game, however, may cause the player to lose equity in the secondary game.
